A study of Georgia residents suggests that those who worked in shipyards during WWII were subjected to a significantly higher risk of lung cancer. It was found that approx. 22% of those persons who had lung cancer worked at some prior time in a shipyard. IN contrast, only 14% of those who had no lung cancer worked at some prior time in a shipyard. Suppose that the proportion of all Georgians living during WWII who have or will have contracted lung cancer is .04%. Fin the percentage of Georgians living during the same period who will contract (or have contracted) lung cancer, given that they have at some prior time worked in a shipyard.
Thanks for any help!!
Well this looks like an exercise in the use of Bayes theorem, so what have you tries??
